孙立东博士为奥地利林茨约翰开普勒大学实验物理研究所副教授,其研究兴趣集中在利用实时原位光谱和显微术实现对固体表面薄膜和纳米结构生长的基础理解和精确控制,在使用光学探针,低温和可变温度扫描隧道显微镜(STM)和荧光显微镜/激光扫描显微镜表征固体表面和薄膜、表面的物理吸附和化学吸附、吸附层的结构和动力学、低维系统中的相变以及纳米结构表面的制备和表征等方面成果斐然。近年来,在Phys. Rev. Lett.Appl. Phys. Lett.等期刊上发表50多篇高水平科研论文,并在国际会议宣读论文40余次。

 

报告内容简介

Differential optical spectroscopy represents a group of versatile techniques for probing surface and interface structure.  These techniques are surface sensitive, non-destructive, not restricted to vacuum conditions and therefore provide significant advantages over conventional surface analysis techniques.  Consequently, these methods are very suitable for the in-situ studies of surface processes occurring under various environmental conditions.

In this talk, the measurement principle will be first introduced. The second part of the talk will be devoted to discussing their application in monitoring and precise control of the growth a nano-structures including metal clusters, organic thin films and 2D transition metal dichalcogenides.  Finally, the new application of the fluorescence microscopy as an in-situ probe for real time monitoring of the growth of organic thin films will also be presented.

差分光学光谱仪是一组用于探测表面和界面结构的通用技术。这些技术是表面敏感的,非破坏性的,不限于真空条件,具有优于传统表面分析技术的显著特点。非常适合于对在各种环境条件下发生的表面过程的开展原位研究。

在本报告中,将首先介绍差分光学光谱仪测量原理,而后将致力于讨论该技术在监测和精确控制纳米结构(包括金属簇,有机薄膜和2D过渡金属二硫化物)的应用。最后,还将介绍荧光显微镜作为原位探针实时监测有机薄膜的生长的新进展。
